Formely known as Chubb crater, the New Quebec Crater has a rim diameter of 3.4 kilometers and is estimated to be about 1.4 million years old. It’s also filled with a 250-meter-deep lake. That’s a big old hole. There’s a whole list of crater locations available at the Earth Impact Database, complete with latitudes and longtitudes… Thanks to Stavro, Michel Bochud and Dominic (from the comments).
